caveats with this comparison, which we will make note of when we present the Integral Test formally. integrals of this type are called improper integrals. Since we can’t simply take the anti-derivative of 1 x and plug in , we do the next best thing. We define the improper integral as a limit: 1 1 x dx lim b b 1 1 x dx. These are not the only type of improper integrals. Others involve If the improper integral is finite, for the infinite series. Proof.

Use variable substitution, u = 3x 6, u" = 3. 3: (3 marks) use the comparison test to show that improper integral. 1: (3 marks) find the area of the region bounded by the graph of y = x2 2x + 1 and the graph of y = 2x2 + 4x + 1. 1.10.4. Comparison Test for Improper Integrals. Suppose f and g are continuous functions such that f(x) ≥ g(x) ≥ 0 for x ≥ 0. (1) If R∞ a f(x)dx if convergent then R∞ a g(x)dx is convergent. (2) If R∞ a g(x)dx if divergent then R∞ a f(x)dx is divergent. A similar statement holds for type 2 integrals. Example: Prove that Z ∞ 0 e−x2 dx is convergent. Answer: We have: Z ∞ 0 e

    Limit Comparison Test A useful method for demonstrating the convergence or divergence of an improper integral is comparison to an improper integral with a simpler integrand. Math 2300: Calculus II Project 3: Comparison of Improper Integrals The goal of this project is to develop \function sense" about the decay rate of functions.

    are both divergent being a multiple of a p-integral with p= 1 2 <1. If we let g(x) = sinpx+3 x and f(x) = p4 x then we have no conclusion since R 1 1 g(x)dxmay improper integral. Consider the in…nite region Sthat lies under the curve y=1=x 2 ;above the x-axis, and to the right of the line x=1:The area of the part of Sthat

    Limit Comparison Test A useful method for demonstrating the convergence or divergence of an improper integral is comparison to an improper integral with a simpler integrand. 7.

    It will not always be possible to evaluate improper integrals and yet we still need to determine if they converge or diverge (i.e. if they have a finite value or not). So, in this section we will use the Comparison Test to determine if improper integrals converge or diverge.

Recall: Integrals Theorem 1. If f(x) is continuous on [a;b] then R b a f(x) dx is integrable. (a) Examples not covered by last case: i. In nite Intervals ii. Discontinuities in the interval 2. Integrals: In nite intervals Proper and Improper Integrals Definite integrals are defined as limits of Riemann sums (Stewart §5.2). Sometimes the limit process breaks down and integral expressions don’t ac-

    Analogous tests work for each of the other types of improper integrals. The Comparison Test suggests that, to examine the convergence of a given improper integral, we may be able to examine the convergence of a similar integral. is an improper integral of type 1 since the upper limit of integration is in–nite. It is also an improper integral of type 2 because 1 x 1 is not continuous at 1 and 1 is in the interval of integration. Example 341 Z 2 2 dx x2 1 is an improper integral of type 2 because 1 x2 1 is not continuous at 1 and 1. Example 342 Z ˇ 0 tanxdxis an improper integral of type 2 because tanxis not

    Evaluating Improper Integrals Learning goal: compare integrals to determine convergence or divergence. Let f(x) be a continuous function, so that Then the improper integrals of f and g with the same limits of integration behave the same way, ie either both converge or both diverge. Since this test for convergence of a basic-type improper integral makes use of a limit, it's called the limit comparison test , abbreviated as LCT .
